I have a carbed 860 in an xm chassis and am looking for a little more. I recently picked up a bondi air box dirt cheap to play around with next winter. I am running the skinz helium hood with their intake shelf and was thinking of running a 3.5" tube from the bondi box to the intake shelf with a filter on the end. Has anyone ran such a big intake on a doo? Just curious what it will do. The skinz tube to the intake shelf is maybe 2.5" so it should increase air flow quite a bit.
